in regards to memory, the linux bigadv units take about 3-5GB (48 core bigadv with 32gb ram)

Aye - Tim_H is right! Much to my surprise the newer, bigger bigadv projects consume less address space than the older, smaller units. On my 80-threader at 74% into a P8101, fah is using 3.1GB; and one 48-threader at 11% into a P8102 (yay), fah is using 2.4GB; and on the other 48-threader at 17% into a P8101, fah is using 2.4GB.
